Stanniocalcin

Stanniocalcin
PFAM accession number:PF03298
Interpro abstract (IPR004978):

Stanniocalcin (STC) is a calcium- and phosphate-regulating hormone produced in bony fish by the corpuscles of Stannius, which are located close to the kidney. It is a major antihypercalcemic hormone in fish. Recent results suggest that the biological repertoires of STCs in mammals will be considerably larger than in fish and may not be limited to mineral metabolism [(PUBMED:11033047)].

GO component:extracellular region (GO:0005576)
